Content

What is Welding?

Welding is the act of joining two plastic or metal parts by melting them together. A person who does welding is called a welder, and welders work in a workshop. Welders must protect themselves from injuries caused by sparks by wearing safety equipment like goggles and helmets.

Items Made by Welders:

• Doors
• Gates
• Toolboxes
• Chairs
• Windows

Welding Equipment

1. Safety Equipment

These tools help protect the welder from injury:

• Helmet – Protects the head from heat and sparks.
• Apron or Jacket – Covers the body from burns.
• Gloves – Keeps the hands safe from hot metal.
• Welding Shoes – Protects the feet from sparks.
• Ear Plugs – Reduces the noise from machines.
• Safety Glasses – Shields the eyes from light sparks.
• Mask or Respirator – Helps the welder breathe safely.

2. Working Equipment

These tools make welding easier:

• Measuring Tape – Measures materials accurately.
• Welding Clamp – Holds materials in place while welding.
• Electrodes – Conduct heat to the metal for joining.
• Driller – Used for making holes in metal.
• Hacksaw – Cuts metal sheets.
• Angle Grinder – Smoothens rough edges.

Board Summary

• Welding: Joining metal or plastic parts by melting them.
• Welder: A person who does welding.
• Workshop: The place where welders work.
• Safety Equipment: Helmet, gloves, welding shoes, goggles.
• Working Equipment: Measuring tape, welding clamp, electrodes.
